Rotons in an optical centrifuge
By Valery Milner on September 28, 2023
Optical centrifuge offers ways to control rotons – collective quantum excitations in superfluid helium.
He dimers in superfluid helium
By Valery Milner on May 14, 2023
Initiating rotational dynamics of metastable helium dimers in bulk He-II allows to study rotational decoherence as a function of liquid temperature.
Roton pairs in superfluid helium

Femtosecond pulses excite roton pairs in superfluid helium, and allow to track their ultrafast non-equilibrium dynamics.
Laser control of chiral molecules
By Valery Milner on April 9, 2019
Optical centrifuge orients chiral molecules, with the direction of orientation depending on the relative handedness of the molecular enantiomer and the rotating centrifuge field.
Ultrafast Gas Magnetization
By Valery Milner on June 19, 2017
Optical centrifuge aligns the electronic spins of paramagnetic super-rotors, producing macroscopic magnetic fields in the gas on a picosecond time scale.
Anderson Localization of Molecular Rotation
By Valery Milner on September 27, 2016
Molecules exposed to intense laser pulses exhibit chaotic dynamics, dominated by the effect of quantum localization.
Gyroscopic Dynamics and Sound Generation
By Valery Milner on September 27, 2016
Molecular super-rotors dissipate their enormous rotational energy into sound waves, detectable by unaided ear

Time-dependent rotational Raman spectra reveal rotational frequencies of laser-centrifuged molecules exceeding 10 THz!
Optical Centrifuge
By Valery Milner on March 4, 2013
Optical centrifuge is a laser pulse whose linear polarization undergoes accelerated rotation, sweeping a corkscrew-shape surface. Molecules line up along the polarization vector and follow its rotation.
